Isn't it annoying how all ladies are always nagging their husbands to turn the thermostat up? (When they aren't having hot flashes, that is.) The CBS Early Show has finally come up with an explanation for this irritating phenomenon which is, no doubt, driving countless temperature-concerned couples apart. Granted, the explanation may not apply to all womenfolk, but don't let that slow you down.

Studies show that compared to men, women conserve more heat around their core organs, so less heat circulates through the rest of their body. Things get even worse at night because the body starts producing less cortisol, a hormone that helps keep the body warm.

Anemia or a low blood count could also be the reason you're always freezing, so if you're the kind of person who thought the Snuggie was a highly necessary invention, you should definitely seek help from a medical professional.

Okay, so this is interesting. But also, as CBS News Medical Correspondent Dr. Jennifer Ashton and Early Show anchor Erica Hill note in this clip, there's a "silver lining" to constantly feeling a bit chilly. Colder temperatures can stimulate the production of "brown fat," which burns more calories. It always comes back to that, doesn't it?

Also, please take note of Dr. Ashton's tips for keeping yourself warm. Though I usually just continue shivering uncontrollably, the next time I get cold I'm going to try putting on a sweater and drinking a warm beverage. Thanks, science.
